Landing Gear/Tail Strike
The landing gear/tail strike function uses these cards:
*
A proximity card
*
An 18 channel driver card.
The landing gear/tail strike function gets inputs from proximity sensors on the nose and main landing gears. This function also gets discrete inputs from the landing gear control lever module and the alternate extend switch.
Discrete signals through the tail strike assembly also go to this function to find tail strike status.

AIR/GROUND SYSTEM -INTRODUCTION
Purpose
The air/ground system (AGS) supplies air mode and ground mode signals to airplane systems.
Components
These are the AGS components:
*
Air/Ground load sensors (4)
*
Weight-on-wheels (WOW) logic cards (2)
*
Air/ground relays.
General Description
Two load sensors on each main landing gear beam send landing gear load data to the two WOW cards.
The WOW cards control air/ground relays in the ELMS. These relays supply air/ground signals to other airplane systems.
The WOW cards also send digital air/ground data through the systems ARINC 629 buses to airplane systems.
Abbreviations and Acronyms
*
ADF -automatic direction finder
*
ADIRU -air data inertial reference unit
